There's a lot of rolling about and rainbow babies in part Two of the Defective Inspector's Let's Play video of Usurper, currently on early release from Pugware...
"There's got to be a change-y weapon-y button somewhere..."

Usurper is a Metroidvania Action-RPG. With Eldritch horrors having been unleashed by the outer-worldly Citadel, your job is to rid London of its terrors. Use the new "Guard" system that rewards skillful play and accuracy, to uncover the massive structure and defeat the nightmares lurking within.
This time on Usurper, the Defective Inspector learns about creepy bug women, gets a monster sword then doesn't know what to do with all his vitae.
